Newbbie Question about Muzishare x7
Dear Stephe and Group,
I am so glad to have found this group!
Stephe's x7 review convinced me about getting one as my first try to returning to the tube world after 45 years (since I built a tube amp). However I have two questions that you may be able to answer given your huge and invaluable experience. I apologize for asking something that is obviously so subjective but I was hopping the measurable (objective) lessons you have learned may be able to generate a couple of answers :
1. If you had to pick a pre-amp for the X7, what would be some recommendations? Or, a link that discusses this. The dishonest full of garbage jungle that web has become is very unpleasant for me.
2. Have you heard any other amp that has made you happier than the X7?
With appreciation and respect,

Reisong A10 mod troubleshooting
Finished doing Stephe's mod to my A10. Fired it up and it works, but my left channel is not as loud as the right. I swapped the EL34's to an Apex matched pair thinking it may be the stock Psvane tubes, but it didn't make a difference.
I'm thinking maybe I have the wrong value of resistor somewhere in the left circuit?
Thanks for any help!

I did the mod a couple years ago and didn’t hear any noticeable balance issues once I upgraded the tubes. The stock tubes were way un-matched. The new tues are matched JJs, and we’re crucial in making my A10 sound fantastic. I didn’t make any changes to her spec, wiring or otherwise. Glad yours is working well now.
Color Preamp Using 6N16B-V Tubes
I have a Vincent SA-31 and re-capped and replaced the tubes with some Russian 6N16B-V's and it sounds fantastic! I have quite a few left over so I am wondering if/how I can utilize them in a modified version of the Color Preamp? I bought a Hammond 262EE6 transformer (120V Sec@ 93ma + 6.3@1.2A) hoping I could use it for this project. Any advice on how the schematic could be modified for their use would be much appreciated!

I think the problem you would run into direct swapping is the anode voltage limitation is 100V I believe?

Glad to hear about the SP14! I will certainly include it in my short list! BTW your builds look beautiful and sound great per your description of absolute silence ;) !!! Regarding the Enyo 15t DAC, can you say anything about the quality of the audio from the HDMI coming from you streaming sources? I have never used a DAC to feed my pathetic integrated (Denon) amp /receiver because there is no point in feeding a good signal in a bad final stage, but i plan to replace my entire audio chain and my questions and your answers are helping me make some low -risk/reasonable decisions.
Thank You for your responses and photos!!!
